Question 2: Write any four applications of electronics in the field of defense.

Answer:

Electronic circuits provide a means of secret communication between the headquarter and different units

RADAR that is Radio Detection and Ranging is the most important development in electronics field. With the help of radar, it is possible to detect and find the exact
location of enemy aircraft, Radar and anti-craft guns can be linked by an automatic
control system to make a complete unit

Circuit boards and sub-assemblies for military firing simulators (anti-tank)

SMPS means switch mode power supply. This works on the principle of switching regulation. The SMPS system is highly reliable, efficient, noiseless and compact because the switching is done at very high rate, in the order of several KHz to MHz.

Question 5: Describe the role of different capacitors in RC coupled amplifier.

Answer:

Coupling capacitor CC is used to connect the output of first stage to the base, i.e. input of the second stage and this continues when more stages are connected. The coupling capacitor CC transmits AC signal but blocks DC.

This prevents DC interference between various stages and the shifting of operating point. The emitter bypass capacitor offers a low resistance path to the signal. Without this capacitor the voltage gain of each stage would be lost.

Question 7: When the two elements of a pair have a surface contact when relative motion takes place and the surface of one element slides over the surface of the other, the pair formed is known as a

lower pair

higher pair

self-closed pair

force-closed pair

Answer: A

Question 8: The static friction

bears a constant ratio to the normal reaction between the two surfaces

is independent of the area of contact, between the two surfaces

always acts in a direction, opposite to that in which the body tends to move

all of the above

Answer: D

Question 9: A shaft has an attached disc at the centre of its length. The disc has its centre of gravity located at a distance of 2 mm from the axis of the shaft. When the shaft is allowed to vibrate in its natural bow-shaped mode, it has a frequency of vibration of 10 rad/s. When the shaft is rotated at 300 r.p.m., it will whirl with a radius of

Question 13: Which of the following is universally employed as the low expansion metal in the bimetallic thermometer, which is an iron-nickel alloy containing 36% nickel and has very low co-efficient of expansion (l/20th of ordinary metals) ?
